From 8da8bd5399cfc2ff98514a6b31a3aa2159516fe6 Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Sat, 2 Oct 2021 14:48:52 +0200 Subject: [PATCH] soc: imx: gpcv2: allow to disable individual power domains Some board designs don't supply power to all of the power domains, as they are not used anyways. In that case we must make sure to not touch those power domains at all, as trying to power up a domain that has no power supplied to it will obviously end in a system crash. Allow to disable those domains via the standard DT status property.
